Inventor: BAZARJANI SEYFOLLAH S
IPC: H03K17/00
Filed: 2000-01-11
Granted: 2009-05-26
Abstract: L'invention concerne une bascule linéaire intégrée dans une bascule à échantillonneur-bloqueur actif. L'échantillonneur-bloqueur actif est symétrique et configuré pour accepter une entrée équilibrée. Deux bascules linéaires assurent le couplage d'un signal d'entrée positif de l'entrée équilibrée sur deux condensateurs d'échantillonnage différents. Une fois que ces derniers ont été chargés, un autre jeu de bascules configure les condensateurs d'échantillonnage pour que l'un des condensateurs d'échantillonnage se retrouve dans la rétroaction d'un amplificateur opérationnel et l'autre soit monté entre l'entrée de l'amplificateur opérationnel et la terre. Grâce à cette configuration, le circuit présente un gain de deux et la sortie de l'amplificateur opérationnel vaut deux fois la tension échantillonnée par les condensateurs d'échantillonnage.

Granted: 2005-05-24
Abstract: A pepper grinding tool with a sideways projecting lever operated with a single hand includes a housing consisting of both an upper part and a lower part, a lever, a grinding assembly and an one-way member.      The housing has a first portion and a second elongated portion projecting sideways from the first portion and having a lateral opening.      The lever has teeth on a front end, and is pivoted to the elongated portion with the teeth facing the first portion and with a rear portion being biased outwardly of the lateral opening by a spring. The one-way member is turnably received in the first portion of the housing, and has a toothed round part abutting the teeth of the lever. The main body is connected to a shaft, of which the lower end is connected to an inner grinding part of the grinding assembly, in such a way that the shaft can turn together with the round part only when the lever rear portion is pivoted outwardly of the opening to force the toothed round part to turn clockwise, i.e. when the user pushes the lever rear portion into the opening and releases the same repeatedly, the inner grinding element is turned clockwise so as to grind pepper distributed between the same and an outer grinding element, which is fixedly received in the first portion of the housing and mounted on the inner grinding element.

Title: Method and communications system for handling a packet service
Inventor: MADEMANN FRANK
IPC: H04L12/64
Filed: 2000-07-13
Granted: 2009-10-06
Abstract: The invention relates to a method and a communications system for handling a packet service with a packet-based core network (CNW) and an access network (ANW). According to the subject-matter of the invention, the control node (EN) which is arranged at an interface between the core network (CNW) and access network (ANW) can control the transmission of multimedia data in the packet data and integrate it into the data transmission from and to the mobile communications device (MS) via the radio interface of the access network. The advantage of the invention is that the control node can actively intervene in the signaling of the transmission of the multimedia data as packet data, i.e. this signaling no longer needs to be carried out transparently with respect to the mobile communications device. A further advantage is that as a result of the integration of the supervision of the multimedia data transmission, the data streams can be better adapted to the radio resources and/or to the requirements of the mobile communications device.

Title: Therapeutic morpholino-substituted compounds
Inventor: ROBERTSON ALAN D
IPC: A61P9/10
Filed: 2001-01-24
Granted: 2011-02-22
Abstract: Morpholino-substituted pyridopyrimidine, quinolone, and benzopyranone derivatives inhibit phosphoinositide (PI) 3-kinase, an enzyme that regulates platelet-adhesion processes. As a consequence, the compounds in question have anti-thrombotic activity, as well as other pharmaceutical properties. The compounds claimed are represented by formula (I), (II) and (III). PI 3-kinase generates 3-phosphorylated PI second messengers which stimulate platelet adhesion under blood-flow conditions. Because platelet adhesion is a necessary step in the formation of a thrombus, inhibition by these compounds of PI 3-kinase under such conditions inhibits or prevents thrombus formation. The compounds are useful in treating PI 3-kinase-dependent conditions including cardiovascular diseases such as coronary artery occlusion, stroke, acute coronary syndrome, acute myocardial infarction, vascular restenosis, atherosclerosis, and unstable angina; respiratory diseases such as asthma, chronic obstructive pulmonary diseases (COPD), and bronchitis; inflammatory disorders; neoplasms including cancers such as glioma, prostate cancer, small cell lung cancer, and breast cancer; and diseases linked to disordered white blood cell function, such as autoimmune and inflammatory diseases.

Abstract: A method of defining header field compression for a data packet connection and a header field compression system, in which a context for controlling the operation of a compressor and decompressor is defined as one parameter of the connection. A length is defined for a context identifier used in identifying data packet connections for data transmission between the compressor and decompressor, said length defining the maximum number of data packet connections transmitted on one connection. Each data packet connection is identified by its own context identifier. The parameters of the connection are defined in such a manner that at least the number of header fields of data packet connections allowed by the defined context identifier length can be compressed despite the fact that the number of data packet connections allowed by said context identifier length is exceeded.
